Cats eating dog food for a long time will cause malnutrition, because cats are pure carnivores, and dogs are omnivores. Their nutritional needs are very different. Dog food is not suitable for cats, but eating less is fine. It won't have much impact. Some parents will give uneaten dog food to their cats. This will not cause any big problems once in a while, but this cannot be done for a long time.

Tip:

Everyone who knows cats knows that it is difficult to choose cat food, and the price is more expensive than dog food. You should choose food based on your own economic situation. The food you choose should be high in protein, low in carbohydrates, and with an appropriate amount of fat. It is best for the protein to be all animal protein, with as few grains as possible. Cat food has no need for carbohydrates. So many. Adult cats will become very lazy. Parents should remember to let cats exercise to avoid obesity.
